The default Debug Console in VS Code doesn't support inputs. You can see all the running threads in the Call Stack pane and work with individual thread using the context menu. Java 9 and newer versions are supported with VS Code Java Debugger as well. You can also attach missing source code with a zip/jar file using the Context menu Attach Source action. Set your breakpoints in those classes before you start debugging. This lets you debug third-party classes when they are inside a JAR or a source attachment. The Java debugger also supports external source files. VS Code can run and debug single Java files without any project. You can also start a debugging session from the Run menu or the Run view opened by the Run icon in the Activity Bar on the side of VS Code.

Redirecting output using > or | should work in Windows from the command prompt in the same way as in a terminal window in Unix. When you'd double-click your JAR file with the program shown, it would open a console window, print "Hello World!" and immediately close the console window again, so you'd only see a console window flash and disappear immediately again. You shouldn't normally do that, and it probably won't really solve your problem. You could probably change this by changing the file extension association in Windows. I don't know if it's easy to change it so that when you double-click a JAR, java.exe instead of javaw.exe will be used. If it doesn't, then something strange is happening. So if you enter "java -jar Test.jar" in a command prompt, it should print "Hello World!" in the command prompt window. When you run your JAR-packaged program from the command line, by executing a command such as "java -jar Test.jar", then it will not use javaw.exe - it will only use javaw.exe when you double-click the JAR file in Windows.
